Next to a big buch of steam-fhs related paths and mesa-12 the following
seem relevant to me:

/nix/store/d0n7lg9xg16wlgs6msgfjwl1fdgsj3af-opengl-drivers/lib/libvulkan_intel.so
/nix/store/948c5kl4snh9jxcq8n8is4ikb1p0hh44-vulkan-loader-1.0.26.0/lib/libvulkan.so
/nix/store/6x9lqyyk48a4x0w5n806r2h0416kn3cb-mesa-noglu-13.0.1-drivers/lib/libvulkan_intel.so

The .so my current booted system is using is the following:

% ls /run/opengl-driver/lib/libvulkan_intel.so
/run/opengl-driver/lib/libvulkan_intel.so -> /nix/store/aqdbc42g8r6l3bm47c8pa2azim8icqbq-mesa-drivers+txc-13.0.1/lib/libvulkan_intel.so*
